Subject[PATCH v1] ALSA: ASoc/tas2781: fixed wrong loading calibrated data sequence
Date
Calibrated data will be set to default after loading dsp config params,
which will cause speaker protection work abnormally. Reload calibrated
data after loading dsp config params.

Signed-off-by: Shenghao Ding <shenghao-ding@ti.com>

---
Change in v1:
- Download calibrated data after loading the new dsp config params
- call tasdevice_prmg_load instead of tasdevice_prmg_calibdata_load, it
is unnecessary to load calibrated data after loading dsp program. Load
it after loading dsp config params.
- Remove tasdevice_prmg_calibdata_load, because it is unnecessary to load
calibrated data after loading dsp program.
- work in bypass-dsp mode even if no dsp fw loaded.
